  5. Site Search Best Practices: A Practical Guide for UK Businesses

Good site search does five things. It is easy to spot, it suggests sensible queries, it returns relevant results, it never leaves a visitor at a dead end, and it works for everyone, including keyboard and screen reader users. Get those right and your search box turns into a shortcut to enquiries. Get them wrong and visitors leave without telling you why.

This guide is for business owners who already have a website and suspect the search box is doing less than it could. You don’t need to be a developer to use it. It is a checklist you can run in an afternoon, plus the reasoning behind each point, so you can brief whoever builds or maintains your site.

TL;DR

  • Put a visible, labelled search box on every page, and keep the visitor’s query in it after they press search.
  • Offer curated autocomplete. GOV.UK found people picked a suggestion in 55% of searches where one was offered, so it is worth doing properly.
  • Never show a blank “no results” page. Offer corrections, broader terms and a way to contact you.
  • Design the results page for scanning, and choose filters only if your content has real categories.
  • Build in accessibility and data protection from the start: persistent labels, keyboard access, and UK GDPR awareness for search logs.

Why site search deserves your attention

Visitors who use search usually know what they want. They are not browsing: they are hunting for a service, a price, a case study or a phone number. If the box fails them, they rarely try a second time. They go back to Google, and the next result may be a competitor.

Search also tells you things that analytics rarely do. Every query is a visitor describing, in their own words, what they hoped to find. If people keep searching for “pricing” and your pricing page calls itself “investment”, you have a naming problem, not a search problem.

Not every site needs a search box. A five-page brochure site with clear navigation can do without one. If you have a blog, a portfolio, a product catalogue, a knowledge base or more than a few dozen pages, search earns its place. For smaller sites, strong menus come first: our guide on why website navigation matters for Leeds SMEs covers that groundwork.

Make the search box impossible to miss

The first best practice is the simplest. Visitors look for search in the top right or centre of the header, so put it there. Show an actual text field on desktop, not just a magnifying glass icon, and keep the icon large enough to tap on a phone.

A few rules that save a lot of grief:

  • Put it on every page. Visitors land deep in your site from Google, not just on the homepage.
  • Make the field wide enough for a typical query. Narrow boxes make people shorten what they type, and short queries return worse results.
  • Label it. A visible label or button text such as “Search this site” removes doubt. More on this in the accessibility section.
  • Use a clear button. A button reading “Search” beats a bare icon for people who are less confident online.

On mobile, the box often hides behind an icon to save space. That is fine, but test that the icon is obvious and that the keyboard opens straight away when it is tapped. If your site is not yet built for small screens, fix that first: see our piece on the benefits of responsive design for business websites.

Autocomplete: helpful when curated

Suggestions as you type have become an expectation. GOV.UK added autocomplete across its search and reported that users selected a suggestion in 55% of the searches where suggestions were shown, with a 92% click-through rate in those sessions. If a government site with millions of visitors finds it worth the effort, a business site with a clear set of services certainly can.

The catch is quality. Nielsen Norman Group warns that suggestions must lead to relevant, high-quality results, and that dumping popular queries from your logs is often unhelpful, because some of those queries return nothing useful. In practice:

  1. Build your suggestion list from queries that return good results, not from raw logs.
  2. Make the suggested text visually distinct from what the visitor typed, for instance by bolding the completed part.
  3. Where it helps, add scope or a category, such as “Case studies” or “Services”, so people know where a suggestion leads.
  4. Limit the list to a handful of options. Ten suggestions is a second search results page.
  5. Check that every suggestion produces results. This takes ten minutes and prevents embarrassing failures.

Search results page design

The results page is where most of the value is won or lost. The best practices are not glamorous, but they are consistent.

Keep the query in the box

Don’t clear the field after someone presses search. People often want to tweak a word, not retype the lot. It also reassures them that the system understood what they asked.

Put the best answer first

Relevance is the whole game. Nielsen Norman Group frames it as two measures: precision, the share of returned results that are relevant, and recall, the share of all relevant content that the search actually finds, as explained in its guide to improving a built-in search engine. You can’t maximise both, but for a business site, precision on the first page matters most.

Two cheap improvements help a lot:

  • Synonyms. If a visitor types “brochure site” and you call it a “business website”, the search should still connect them. Search engines without synonym and basic stemming support, such as treating “reducing” and “reduction” alike, create friction that sends visitors elsewhere.
  • Best bets. If you know the right answer to a common query, pin it. Nielsen Norman Group suggests blending curated results into the main list rather than boxing them off as a promotional block, because users have learned to skip anything that looks like an advert.

Make each result scannable

Each result needs a clear title, a short snippet showing the query words in context, and enough information to tell page types apart. A service page, a blog post and a PDF should not look identical. Show the page type, a date for time-sensitive content and a thumbnail where images help, as with portfolio items or products.

Key elements of a scannable search result

Show how many results there are

A line such as “24 results for ‘logo design’” sets expectations. Add pagination or a “load more” button, and keep the total visible so people know how deep to go.

Filters and sorting: only where they earn their place

Filters are brilliant on a catalogue with hundreds of items, and clutter on a site with thirty pages. Add them only when your content has real, consistent attributes such as service type, sector, location or date.

If you do add them, decide how they behave. Nielsen Norman Group describes two models: interactive filtering, which refreshes results after each selection, and batch filtering, which waits until the visitor has made all their choices. Interactive suits visitors who are exploring. Batch is the safer choice on mobile or where your search is slow, because it cuts the total waiting time.

Situation Better choice
Fast search, visitors browsing and comparing Interactive filters
Slow search backend or heavy pages Batch filters with an “Apply” button
Mostly mobile visitors Batch filters
Few pages, little variety No filters at all

Whichever you choose, show which filters are active, and give a single “Clear all” action. Nothing frustrates a visitor more than being stuck in a filtered view with zero results and no idea why.

Never leave visitors at a dead end

A “no results found” page is where visitors give up. Nielsen Norman Group’s guidance on no-results pages is to give people a way forward: suggest spelling corrections, propose similar queries, advise how to broaden the search, and keep the original query in the box so it is easy to edit.

A decent no-results page includes:

  • A plain statement that nothing matched, using the visitor’s own words.
  • A “Did you mean” suggestion for likely typos.
  • Two or three popular pages or categories.
  • A short tip, such as trying fewer or more general words.
  • A contact route: a phone number, email address or short form. For a service business, this is the most valuable line on the page, because it turns a failed search into an enquiry.

Then review these failures. List the zero-result queries every month. Some will be typos, some will be content you should write, and some will be words your customers use that you don’t. All three are useful.

Accessibility is part of search, not an extra

A search box that only works with a mouse or sighted use is a search box that fails a share of your visitors. Public sector bodies in the UK have legal accessibility duties, and although a private business is not bound in the same way, the same standards are the sensible benchmark for any commercial site. Our article on why website accessibility matters for UK business success sets out the commercial case.

For search specifically, check these:

  • A persistent label. Screen readers may announce an unlabelled box as a generic edit field. Use a real label such as “Search this site” rather than placeholder text, which disappears as soon as you type and often has weak contrast.
  • Keyboard access. You should be able to reach the box, type, move through suggestions with arrow keys, select one with Enter and close the list with Escape, without touching a mouse.
  • Announced suggestions. An autocomplete list is a combobox. Dynamic suggestions need the right ARIA roles or live regions, or they stay invisible to screen reader users.
  • Visible focus. Keyboard users must see where they are, in the box and in the results list.
  • Meaningful result links. “Read more” repeated twenty times tells a screen reader user nothing. Make the link text the page title.

The quickest test costs nothing: put your mouse away and try to search your own site with the Tab key only.

Data protection: your search logs are data

Most owners don’t think of search as a data issue, but visitors type all sorts of things into a box, including names, order references and personal circumstances. If those queries are stored, they can become personal data under UK GDPR.

Sensible habits:

  • Log only what you need to improve results, and decide how long you keep it.
  • Don’t log IP addresses alongside queries unless you have a reason.
  • If you use a hosted search service, check where the data is processed. If it leaves the UK or EEA, you need an appropriate transfer mechanism, such as an International Data Transfer Agreement or the UK Addendum to the EU standard clauses.
  • If you add AI-driven search, ask the provider whether your data is used to train models, and get the answer in the data processing agreement.

If your site handles sensitive enquiries, speak to a data protection adviser before switching on query logging. The ICO’s own guidance is the authority here, not a plugin’s settings page.

Search and SEO work together

Internal search and Google search feed each other. Your search logs show which phrases visitors expect to find, and those phrases are good candidates for page titles, headings and new content. Pages that rank well but fail on-site searches often have a labelling mismatch.

Two practical points. First, make sure internal search result pages do not flood Google’s index with thin, duplicate pages: a developer can set them to be excluded. Second, use the logs to plan content. If you are building out your own content plan, our guides on SEO best practices for UK small businesses and boosting your online visibility are a good place to start.

A 30-minute site search audit

You don’t need software for a first pass. Set a timer and work through this list.

  1. Find the box. Open your homepage and an inner page on your phone. Can you find search within three seconds?
  2. Search ten real queries. Use words your customers use: your top services, a price question, a location, a misspelling.
  3. Judge the first page. Is the right page in the top three for each?
  4. Type slowly. Do suggestions appear, and does each one lead somewhere useful?
  5. Search nonsense. Look at the no-results page. Is there a path forward and a way to contact you?
  6. Tab through. Can you complete a search with the keyboard alone?
  7. Check the log. If your site records searches, read the last month of queries and the zero-result ones.
  8. Write down three fixes, ranked by effort. Do the easiest first.

Repeat it quarterly. Search quality drifts as you add and rename pages.

Our perspective: search is part of the brand experience

We build websites for small and growing businesses, and we see the same pattern often. A business invests in a good logo, a clear identity and a well-designed homepage, then the search box inside it looks like an afterthought: default styling, vague labels, a bare “0 results” message. Visitors notice. It is a small moment, but it is the moment someone is actively trying to give you their attention.

Our view is that search should sound like you and look like you. The no-results message is copy. The suggestion list is a design decision. The label is an accessibility decision. Treat them as part of the brand, and handle the technical side, synonyms, filters and logging, as part of the same build rather than a plugin bolted on later. That is why we work as one team across creative design and technical delivery: the people choosing the typeface are in the same conversation as the people configuring the search.

If you take one thing from this guide, make it this: start with your own search log and a ten-minute test. You will learn more than from any checklist.

FAQ

Not always. If your site has fewer than about ten pages and clear navigation, a search box adds little. Once you have a blog, a portfolio, a large service list or a product catalogue, search helps visitors who know what they want find it quickly.

What is the most important thing to fix first?

Start with the no-results page and the labelling. A page that offers corrections, popular links and a contact route turns failed searches into enquiries, and a persistent label helps every visitor, including those using assistive technology. Both are quick to change.

Should I use autocomplete?

Yes, if you can curate it. GOV.UK’s data shows people use suggestions heavily when they are offered. Make sure every suggestion returns real results, otherwise autocomplete just leads people to dead ends faster.

Are my site’s search logs covered by UK GDPR?

They can be. Visitors sometimes type names or other personal details, which makes the stored query personal data. Keep logging minimal, set a retention period and check where any hosted search provider processes the data. For sensitive sites, take advice from a data protection professional.
